Creation of New Base Unit of Measure

Hi Forum, does anyone have any detail on how to go about creating new units of measure and what to look out for? Any documentation would be appreciated.
I know the Tcode (CUNI) and to copy certain existing BuM's but was wondering about the ISO and whether i actually need to apply for this as we wont be using EDI with our Vendors. Any best practice or guidance to be aware of would be highly appreciated.
Thanks
Dan

Generally, if you are creating new Uom same as like exisitng one and you are not using the EDI than you are file with ISO code but if you are planning to use EDI than you can search for ISO code on Google. If the Uom is standard other wise you have to use the exisitng which can match some percentage to your Uom

Base unit of measure

Dear Expert
my query is whenever i add new base unit of measure what are the effect it had on the system , i mean how base unit effect in the back end ...how system process base unit of measurement .
Regards

Dear usmfarhan
Actually Base unit of Measurement is the UoM which u want to maintiain ur inventory in the system.
i.e whater u r buying it from vendor ...it might be in Ea or Box or Carton
And you want to store in KG
So you can have Additional unit of Measurement and its conversion that can be defined in AMterial master in additional unit of measurement
Let us say Base UoM is KG and ur Ordering unit is TON
So u have to define Conversion rule as 1 Ton = 1000 KG in material master.
,While changing Base unit of measurement you should make sure that stock should not be there.
Secondly neither Purchase order for Raw material not Sales order for FG should exist in the system ,Neitehr routing should exist for FG
Or else system will not allow u to change UoM

Changes in Base Unit of Measure

Hi,
We got an issue,User tried to change the Base unit of Measure from NO to KG.
1.For this material we dont have stock in unrestricted and quality,But it has reservations. 2.It has got Scheduling agreement,3.This material is used In BOM.
So if i cancel reservations,then remove this item from scheduling agreement and delete it from BOM.Will it work further to change the Base Unit of Measure.
Please Do help me in this matter
Thanks and Regards

1) You can only change the base units of measure under the following circumstances
No stocks are available for the material.
There are no existing purchase requisitions, purchase orders, or scheduling agreements for the material.
At present, no purchase orders or purchase order items are being created or changed.
Item is not linked in any BOM as chield part
If requests for quotations, purchasing info records, or contracts are available for a material, the system emits a warning while changing base unit of measure. Still if you want to change unit of measure specify in a dialog box the factor for converting the base unit of measure into the new base unit of measure. The purchasing info records are then, if necessary, updated.
2) Solution
   As system is not allowing changing base unit of measure there will be either stock of this material or existing purchase document
1) If there are stocks in the previous period, you can clear them as follows:
a) Post the stock in the previous period to the current period (for example, using movement type 561) so that the stock for the previous period is the same as the stock for the current period.
b) Clear the stock with the posting date in the previous period (for example, using movement type 562).
2) If there are Open purchase requisitions, purchase orders, or scheduling agreements for the material.complete all P2P cycle for open orders (purchase requisitions, purchase orders, or scheduling agreements) and then close it.
3)Delete item from BOM
Then
1.     Run Trnx MM02 (Change Material Master immediately.
2.     Overwrite the old base unit of measure with the new one in basic data screen.
3.     Save the change.
3) System checks
If a change criterion (Trnx. code MM02) is meeting all necessary prerequisites (as mentioned in point 1).System allows changing base unit of measure. Otherwise it displays warning or error. U can display the reason for this, by choosing Display Errors (ctrl+F1)

Base unit of measure is cahnging after creation of material master

Hi
I have created a material with material type Raw material with BUM "Ton" , after save the material, when iam checking the material with display mode, the BUM is changed into "EA",i dont know where the sustem picks the BUM as "EA", kindly suggest where i have to do the configuration settings.
Thanks

Hi,
Have you created the New Material referencing from another material.
Please check the following links for details. It should be able to answer your queries.

Base unit of measure Box is missing in SAP 4.7

Dear Group members
Base Unit of Measure "Box " is not in my SAP System 4.7
Dear Group Member
I am not finding "Box " Base Unit of Measure in my system
My system is SAP 4.7
You suggestions will be appreciated

Go to CUNI Tcode
and select the existing any UOM which is proximate to Your BOX unit of measure.
and Copy it as and Name it BOX
OR
Creation New Unit of Measure
Use transaction CUNI t create UOM
Here click UOM & then in the next screen click create icon in the top.
Steps,
1: use CUNI tode create Dimension give Dimension text and unit
2: create a IS code
3. in unit of measure option give commercial and technical information
I hope that this will help u for create unit measure

Follow up material with different base unit of measure

Hi all,
I have the BOM with material Mat1 as a component. The base unit of measure of Mat1 is KG.
Is it possible to replace Mat1 with Mat 2 material in MRP once the Mat1 warehouse stock is depleted.
The base unit of measure of Mat 2 is KGK.
The required quantity of MAT1 should be recalculated from KG to KGK accordanly unit ratio.
Please, expain, where does it maintain?
Thanks,
Peter

Hello Peter,
You can use follow-up setting (set Mat2 as follow-up of Mat1 in MRP 4 view of material master if this follow-up scenario is valid for all BOM) with discontinuation indicator '1', w/o effective-out date. In this case Mat1's stock will run out (no PldOrd, PR, etc) will be created, and from the date, when Mat1's stock runs out, MRP will calculate with Mat2.
As I told you, according to my best knowledge, you cannot realize this with different base unit of measures. (you have to change the buom of one of the related material masters or create a new material master if you cannot cope with buom-change).
Follow-up group scenario can also be used but I guess different buoms will be a problem in that case as well.
Maybe there are better solution but I'm not aware of it...

Base unit of measurement while saving production order

Hi
While saving production order I am getting following problems:
"Material has no base unit of measure"
Whereas UOM is there, I also can see that as soon as I enter qty while creating the order. System automatically prompts the UOM.
I also donot find any problem in MRP run, planned order creation etc
So what can be the problem?
Edited by: BNR on Nov 24, 2008 5:22 AM

Dear,
It may be data base problem as you are getting this problem fequently so please check with Basis person.
Have you defined the any production unit in both material master WS view & in routing or any other alternative unit of measurement please check?

Changing Base Unit Of Measure (Material Master)

Hi
1. How to check this? (Any successful changes in material master only took place when there is no open document from SD, PP, MM & FI for that material. )
2. Base unit of measurement cannot be changed. The reason being material movement history is there in table - MSEG mainly which otherwise create inconsistency in reporting. -
Is this line applicable for current period or previous period in current year or previous period previous year???
3. There are no existing purchase requisitions, purchase orders, or scheduling agreements for the material. -
is this means open / pending purchase orders or the the PO's created in system with respect to material where the GR and IR is already done
4. You can change the base unit of measure if there is no stock of the material during current and previous period----
is this means the term " previous preiod" is previous period in the current finacial year   or its applicable for the previous preiod in previous financial year
5. Post the stock in the previous period to the current period - -
how can we do this???
Vijay

See this OSS note : especially the last sentence:
From OSS note 138767
Within the material master record maintenance, you want to change the base unit of measure (base unit). During the change, the system performs extensive checks in order to avoid inconsistencies in the applications which use the material master.
In particular, the following checks are performed:
The base unit must not be defined as an alternative unit of measure for the material
No International Article Number must be assigned to the base unit
No proportion/product units must be defined for the material
No configurable material must be assigned
The material must not be used as a configurable material
Stock must neither exist for the previous period nor for the current period
No physical inventory must be active
No reservations or dependent requirements must exist for which the deletion indicator is not set
No planned orders must exist
No purchase requisitions, purchase orders or scheduling agreements must exist for which the deletion indicator is not set
No WM transfer requirements, no WM quants or no WM posting change notices must exist
The material must not be a bill of material
The material must not be contained in a bill of material
The material must not be used as a production resource/tool
The material must not be used in task lists
No standard cost estimate must exist for the current or future period
No production orders must exist
No planned independent requirements must exist
No run schedule headers must exist
If the base unit has dimensions, no serial number profile must be assigned
No sales and distribution documents must exist which have status Not processed or Partially processed.
Solution
If necessary, all reasons mentioned above must be eliminated by archiving the objects listed
1) SAP checks this for you. A new button will appear in MM02 and after you click this button to check the error log, you will see which documents exist.
2) I have not seen that an existing movement will restrict the change of a BUoM.
3) No purchase requisitions, purchase orders or scheduling agreements must exist for which the deletion indicator is not set
       it is not caring about GR done or IR done. it telling you that the deletion indicator has to be active. As a deletion indicator can be reset easily, you probably have to archive the documents
4) the previous period is the period before the current period.
   today we have February, hence the previous period is January.
5) first make sure your current stock is higher than the stock of the previous period. if it is lower, then you have to create inventory in current period first e.g. with 202 movement with current date.
Then you issue the previous period stock with 201 movement and previous period date (make sure periods are open in OB52 and MMRV allows posting to previous period).
Finally you issue the left stock in the current period with 201 and current date.
Now previous period and current period stock is zero. After the change of the base unit you have to get the stock back into the system

Change base unit of measure

Hi,
Its me again. I need to change the base unit of measure of a material but a task listw as created via QP01. I tried to delete this via QP02 but i still cannot change the base unit of measure. Is there any way except for deleting the task list via CA98?
Thanks.
Elen

Ellen,
Unfortunately the answer to your question is no..You have to use a transaction like CA98 or QSR6 to delete the Inspection plan from Database. Please take necessary authorisation and delete this plan.
Alternately set this material to with deletion flag and client & plant level status, so that you cannnot use this material any longer. Now create a new material with correct Base unit of measure and use this material.

Base Unit of Measure to Sales Unit Conversion

Hi,
Currently we are selling material in MT and all other transactions in MM and Production are in MT only.
Now client wants material to be sold in Meters, also in some cases the same material will be sold in MT also.
(As per my knowledge generally if the conversion is one to one i.e. base unit of measure is pieces and Sales unit of measure will be boxes and
1 box = 10 pieces can be maintained in material master.)
Here for conversion between Metric tonne to Meters there is formula involved so how and where this conversion needs to maintained in system.
How to map this type of scenario.
What all activities needs to be done from SD side and which other modules need to be involved this process.
Note: SAP is installed for more than 3 years now.
Hope i clear enough.
Regards,

Hi following is the formula.
OD = Outer diameter, thickness, length, Number of tubes are maintained in sales order charateristics during sales order creation.
OD
Thickness
Weight in Kgs / M
length of tube
Nos of tubes
Total length in Mtrs
Rate / MT
Rate / Mtr
A
X = (A-B)*B*0.02456
'L
N
T= L xN/1000
R
M=R/1000*X

Base unit of measure issue during CIF

Hello,
we have one APO system which is connected to two R/3 systems (System A and System B).
Actually one product number was coming years ago from System A with base unit of measure EA.
We now need to add the same product number (with a different Business system group) via CIF coming from system B, but the source base unit of measure is ST.
CIF interface stops with error "Error Text: Base unit of measure for product xxx" ....
So actually I am looking for a way to add product xxx to the integration model in System B and transfer data to the APO system without removing the products and all linked master and transaction data from APO and creating new data.
Maybe there is a workaround ...
Thanks for any ideas and thoughts.
Kind regards,
Andrea

Andrea
One way is to add ST as alternate unit of measure in APO product master . This is because you cannot change the base unit of measure in APO without deleting all the dependent objects.
After that you will be able to CIF over the data . But then you have to remember one thing . Whenever you change the material master for this material in R/3 and CIF it over , the alternate UOM ST will get wiped out in APO and you have to maintain it manually.
Thanks

Base unit of measure is different from Idoc to purchase order toSAP System.

Hi Gurs,
vendor send a purchase order for confirmation through EDI, the base unit of measure in the Idoc is PA( Parcel). For this same material the unit of measure in R/3 system is PC.( Piece). I got a error on this.I checked in CUNI, In Unit of measurement ST (PC) is already assigned to unit PCE in EDI. But i dont want to change the Conversion.I need this also and I want to create a new conversion ST(PC) is assign to PA( Parcel).
Please help in this.
Is it possible to maitainthe ISO-code PA into table Units of Measurement of Dimension?
Edited by: Vadivel Karalam on Nov 1, 2010 1:13 PM

Hi,
You are getting the error because as part of the std ( For ALE/EDI) the unit of measurement that is maintained is PC whereas if you look at another unit of measure that you have mentioned, the std doesn't define anything under the ALE/EDI setup.
Because of that all the conversions are coming with PC. So pls goto general settings and check unit of measure menu. There for each of your units, there is a section for ALE/EDI, set up the relevant UoM and the issue should get resolved.
Hope it helps.

Base Unit Of Measurement error

Dear Sir \ Mam,
Our some materials base unit of measurement is in KG, and we want to make bills, excise RG1 entry in KG for milligram sales or material transfer. How to go for such transaction, system is not allowing for such transactions.
Pls Note : We can't create two separate materials code for these UOM issue materials.
Requesting a help.
Regards,
Randhir Padwal

Hi,
As per my understanding you have base unit in KG and you want to material issue and sales in miligram unit. If this is requirement then you may try to assign "sales unit" for material master in "sales:sales org1" view. you have to also give the conversion rate from KG to miligram in additional data.
for issuing you have to maintain issue unit "miligram" in material master view "Plant data/stor1"

Material Master MATMAS IDOC and base unit of measurement

Hi
We are using SAP standard material master IDOC type MATMAS05 to trigger IDOC. Our material master is having base unit of measure as "G". We are not using ISO unit of measurement. But Material master IDOC, segment E1MARM is populating base unit of meaurement (MEINS) as "GRM".
Any idea why IDOC is picking ISO unit of measurement instead of material master base unit of measurement.
Any idea how to send base unit of measurememt as "G" instead of "GRM" in DOC segment.
Thanks
Nilesh

There are ISO codes for country keys, currency keys, units of measure and shipping instructions. According to SAP design guidelines, you should use ISO codes for an IDoc if they are available. When you set up the IDoc, the SAP codes have to be replaced by ISO codes.
